Place the cold heavy whipping cream in a medium size bowl. Using an electric mixer, beat the heavy whipping cream just until soft peaks are formed.
In a separate medium size bowl, whisk together the sweetened condensed milk, vanilla extract, and salt.
Using a spatula, gently fold in the whipped cream to the sweetened condensed milk mixture. Once combined, pour into a loaf pan and cover with plastic wrap.
Freeze for 3 hours and remove from the freezer. Using a spatula, carefully mix in the frozen cookie dough balls and 1/2 cup of mini chocolate chips. Cover with plastic wrap and freeze for an additional 3 hours, or until fully frozen.
